The MCS350 is just pumping "dialtone" down that pair all the time.

<p class="MsoNormal"><span style="color:#1f497d">A station port would need to supply talk battery to the station, so yes that would need FXS, but no that’s not what I want.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="color:#1f497d">Basically I was trying to get a dry audio output for an overhead paging system. Kinda like you would with an E&M port, but I only have the FXO ports. The idea was for this to be a temporary workaround – contractor
is installing a new paging system to replace a failed one but they are missing the module they need to interface with a telephone port, so in the meantime all they can accept is a dry audio feed.<u></u><u></u></span></p>
